Question from a reader:
" Hello! Please tell us how to comply with the requirements on the use of the air conditioner at least once a month (for his long and trouble-free operation), with the proviso that it is frost on the cars is not included? "
Interesting question, today's article will name - conditioner prevention ...
Air conditioning in the car thing as they say capricious, her keep an eye. If the car you have a new service that will be undertaken by the official service station. See test the system, etc. In general, the car air conditioning system must necessarily look after each winter. Winter passed, drove to the dealer or a third-party stations (no guarantee) tested the system before summer and drive safely.
Why after the winter to call in air conditioning diagnostics?
This will be the prevention of the air conditioner. As said above this device is very moody, the system has a bunch of pipes, the connecting rings conditioner radiator and to the engine (compressor) into which oil is added. The thing is, that even new car pressure in the air conditioning system may be slightly fall during the winter period.
If you drive a car with air conditioning the first year, then can you not even notice, it will be slightly worse than frost. But if you have not stopped by to prevent 2 or 3 seasons, the pressure may drop significantly, even in the intact system. And it may fall so that the air conditioning in the car will not turn on. Can not be included because of its protection system, the system sees that the system pressure is insufficient and is therefore not included. Everything is simple, it is necessary to bring the system pressure to the desired level, and then the air conditioner will be turned on. That's right, I had on my FORD FUSION.
Why C pressure falls in the winter?
From the temperature difference. The fact that the system has not fully metal tubes, where they have rubber seals, these places a little, but they are the most vulnerable. From low temperature rubber can not be compressed significantly, so in the system liquid (Freon refrigerant), which is under pressure can slightly escape through such spacers. This is normal, as they say the producers themselves, the permissible level of pressure drop in the system is always present. Any specialized station you will restore the pressure for a few minutes, and they have the data on your air conditioner and the material for your system. Remember that the pressure in the different systems, so it is best to call in a specialized (for your brand) station.
Next important step in the prevention of the issue - is the purity of the radiator. Radiator conditioner is usually located near a vehicle radiator, and it is clear that over time it becomes clogged with dirt, dust, fluff (for example - in July of poplar), etc., it should be cleaned.
Otherwise, your air conditioner will not be well enough to cool the passenger compartment, and you'll rack your brains. Just go to the car wash, if necessary, remove the front grille and clean wash conditioner radiator. We see a lot When I washed on his FORD FUSION did not think that there's so much dirt.
Also conditioner prevention should include compliance oil level and its timely replacement. It should be noted that the oil should be changed infrequently, because the air conditioning is only in the summer, also have no contact with the oil components which have a very high temperature, like the engine, for example. Therefore, the oil changed every few years, usually (5 - 7), the main thing that the oil is, but if not, then you may lose your compressor, it simply fails. Also, oil is better not to "borsch", the oil should be just as much as is specified in the vehicle tank or instructions. If you add oil to the compressor tank, it must be exactly the same brand, remember that. Usually grade indicated in the instructions to the vehicle. Now let's talk about the operation of the winter.
Air conditioning in the car in winter
As you have correctly noticed, many cars in the winter air conditioning is not turned on. Having said that what I wrote above, the gum system, and so the oak, and give you more pressure, then your cooling fluid is twice will go faster. YES and pressure Freon greatly decreases. And what is the need to include air conditioning in the winter? On the street and so "Dubakov". However, the inclusion of winter is still necessary. It is for prevention. The device is, as it were in a dead state, the compressor does not work, oil and coolant is not running on the system, this is not good, the compressor can rust and some of the details, but this is not a "gud". Therefore, to work in the winter and as stated by the manufacturer is sufficient once every 1.5 - 2 months, that is, it turns out during the winter and early spring 2 - 3 times the air conditioner served longer. But turn the air conditioner if the outside - 25, and he is no longer activated when - 5? Here, as the saying goes, you need savvy. You need to drive the car in a warm box, or parking - parking. Such large cities can be easily found, the vehicle must warm up at least half a day, and then turn on the air conditioner and let it run for about 20 - 30 minutes, during which time the system is well banish the oil and coolant. Only in this way, and not as a, you can turn it on.
